SRP + Sandboxie problem

Am using SRP on my Windows XP SP3 (x86) as described here http://www.mechbgon.com/srp/ with additional changes as described
here -http://ssj100.fullsubject.com/t4-ssj100-s-security-setup-

As far as Sandboxie is concerned I've set it up as described in the second
link above with additional changes as described here in the 4th post -http://ssj100.fullsubject.com/t88-newbie-sandbox-setup-help#488-

Now the problem is, I cannot execute any exe in the Sandboxed Downloads
folder even as Administrator. Its giving me SRP restriction error. I can run all other files except exe.
Note that I can run any exe files in the unsandboxed Downloads folder as an Administrator.

Thanks alot, I disabled drop rights in SB and the problem is solved.
However I noticed that if I delete any files from the Sandboxed
Downloads folder it does NOT get deleted from the real Downloads
folder.
